How to determine if a process is running using Python for Win and MAC

Question

I am trying to find a way to determine if a process is running in Windows Task Manager for Windows and Monitoring Macintosh activity for MAC-OS using Python

Can someone please help me with the code please?

Answer 1

psutil is a cross-platform library that retrieves information about running processes and system usage.

import psutil pythons_psutil = [] for p in psutil.process_iter(): try: if p.name() == 'python.exe': pythons_psutil.append(p) except psutil.Error: pass 

 >>> pythons_psutil [<psutil.Process(pid=16988, name='python.exe') at 25793424>] >>> print(*sorted(pythons_psutil[0].as_dict()), sep='\n') cmdline connections cpu_affinity cpu_percent cpu_times create_time cwd exe io_counters ionice memory_info memory_info_ex memory_maps memory_percent name nice num_ctx_switches num_handles num_threads open_files pid ppid status threads username >>> pythons_psutil[0].memory_info() pmem(rss=12304384, vms=8912896)

In stock Windows Python, you can use subprocess and csv to parse the output of tasklist.exe :

 import subprocess import csv p_tasklist = subprocess.Popen('tasklist.exe /fo csv', stdout=subprocess.PIPE, universal_newlines=True) pythons_tasklist = [] for p in csv.DictReader(p_tasklist.stdout): if p['Image Name'] == 'python.exe': pythons_tasklist.append(p) 

 >>> print(*sorted(pythons_tasklist[0]), sep='\n') Image Name Mem Usage PID Session Name Session# >>> pythons_tasklist[0]['Mem Usage'] '11,876 K'

This disables the eryksun Windows solution, discards the csv import, and filters the task list directly for the exe name:

 def isWindowsProcessRunning( exeName ) : import subprocess process = subprocess.Popen( 'tasklist.exe /FO CSV /FI "IMAGENAME eq %s"' % exeName, stdout=subprocess.PIPE, stderr=subprocess.PIPE, universal_newlines=True ) out, err = process.communicate() try : return out.split("\n")[1].startswith('"%s"' % exeName) except : return False
